First Watt F7- preamp question

My apologies ahead of time if this post isn't appropriate, but I was wondering if any First Watt F7 owners (or the DIY variants) know if it will pair well with a Schiit Freya+? As usual my interweb searches yield both positive and negative views... and almost every most other places like reddit tell me to try the diyaudio forums. 🙂

TIA!
